13. Add the following import statement.
import net.connectcode.*;
14. Find the following line in the constructor of the file
initComponents();
15. Add the code marked by "// TODO" in the function. The code uses the barcode fonts JAR library to create barcode output characters. These characters are then used in jLabel1 together with the "CCode39_S3.ttf" barcode font. Use the "CCode39_S3_Trial.ttf" is you are using the trial version.
initComponents();
// TODO
initComponents();
Code39 code39=new Code39();
String outputStr=code39.encode("12345678", 1);
//String humanTextStr=code39.getHumanText();
jLabel1.setText(outputStr);
jLabel1.setFont(new java.awt.Font("CCode39_S3",java.awt.Font.PLAIN,24));
16. Click on the "Design" button.
17. Increase the boundary size of jLabel1.

10. Add the following code to the Demo.java class. The code first creates JFrame and JLabel objects. This is followed by using the Code39 class in the barcode fonts library and the "CCode39_S3.ttf" font file to create a barcode.
public static void main(String[] args) {
JFrame frame = new JFrame("ConnectCode Barcode Software Demo");
JLabel jLabel1 = new JLabel();
Code39 code39=new Code39();
String outputStr=code39.encode("12345678", 1);
//String humanTextStr=code39.getHumanText();
jLabel1.setText(outputStr);
jLabel1.setFont(new java.awt.Font("CCode39_S3",java.awt.Font.PLAIN,24));
frame.setSize(400, 400);
frame.setVisible(true);
frame.add(jLabel1);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
